Composition and properties
Stainless steel AISI 317L (1.4438) is a low carbon austenitic alloy with a high chromium content (18%) and Nickel (13%). The percentage of carbon in steel does not exceed 0.03 percent, and it is fully bound with iron, presenting a solid solution of cementite in the basic metal matrix. From similar grades of steel characterized by a higher (3%) molybdenum content.
Depending on the country of origin composition of steel varies, which follows from the table (the rest is iron):
| Country | Standard | Carbon | Chrome | Nickel | Molybdenum |
|---|---|---|---|---|---|
| USA | AISI | 0,03 | 24…26 | 22 | 0,75 |
| Russia | TU | 0,03 | 19 | 13 | 3 |
| Germany | DIN | 0,02 | 20 | 18 | 5 |
| Japan | JIS | 0,035 | 18…20 | 11…15 | 2…4 |
The chemical composition of the alloy determines the following features:
- Improved resistance against corrosion, including high temperature.
- High has acid resistance.
- Strength at elevated up to 1300…18000 temperature long-term operation of products.
- The strength under sustained loads not exceeding the limit of tensile strength.
- Satisfactory weldability.
When melting in vacuum furnaces additional alloy is saturated with nitrogen, which is then bound in high strength chromium carbides. The presence of molybdenum promotes the formation of intermetallic compounds, which further improves heat resistance.
Application
Pipe in stainless steel AISI 317L (1.4438) is widely used in the manufacture of pipelines, which systematically pumped liquid aggressive environments, including at elevated temperatures. Growth and development point sources of corrosion in this case is slowed, which leads to increased service life of pipelines. Consumers — gas and oil-refining industry, and manufacturing various chemical reagents, plant protection products, pharmaceutical intermediates., etc.
The range of this alloy (domestic substitute — steel 03Х19Н13М3 produced by a special TU) is used in the manufacture of a highly resistant reinforcement. Thus implemented the technology of cold forging, hot forging.
Wire of AISI 317L (1.4438) used in high-precision measuring instruments and equipment, which performs continuous monitoring of the steelmaking complexes.
